The Trinamool Congress in Manipur also merged with the BJP on Friday. Accordingly, its lone MLA, Robindro Singh, is now a BJP legislator, taking its strength in the 60-member house to 28.

T. Shyamkumar was the first Congress MLA to join the BJP after the assembly elections. He was sworn in as a cabinet minister on March 15. Shyamkumar was followed by Ginsuanhau Zou.

In the March election, the Congress, which was then in power, bagged 28 seats to finish as the single largest group.

But the BJP, which secured 21 seats, joined hands with other parties to form the government.

State Congress President T.N. Haokip said: "Things have changed after the election. Friends have become foes. There is nothing called principle or ideology. Those who crossed the floor are not afraid of disqualification."
